Title: Quantitative analysis of analyte concn. or enzyme activity in liq. - by photometric determn. of reaction velocity of a coloured prod. formed in presence of analyte or enzyme
Inventor: AMANO YOSHIKAZU
IPC: C12Q1/00
Filed: 1987-03-06
Abstract: In the quantitative analysis of the concn. of an analyte or of the activity of an enzyme contained in a liq. sample, the reaction velocity is assayed by the photometric determn. of a coloured prod. which is formed in at least 2 steps in the presence  of an analyte or enzyme. In the 1st step (1), a correlation equation is set up between an optical density of a coloured prod., which is measured at the moment To after the starting-time of the reaction, and a value of the decrease of the optical density during the time To and a given time T or an average value of the decrease of the optical density per unit time. At least 2 reference solns. are used, contg. an initial cpd. of the reaction for the analysis or an intermediate prod. in a known concn. or activity. (2) The values of the optical density of a coloured prod., prepd. by the effect of the analyte or of the enzyme in the liq. sample at the time to after the starting-time of the reaction and at the time t after the to, are measured. (3) The value of the optical density at the time to is introduced into the correlation-equation above, so as to calculate value of the variation delta at the time t. (4) The concn. of the analyte or the activity of the enzyme in the liq. sample is determined quantitatively by an assay of the reaction velocity. The value delta above is used as correlation-value for varying the optical density between twofold measurement in step (2), to and to + t. USE - The determn. of the concn. or of the activity of a specific component in a liq. sample, e.g. blood, is important in clinical tests. E.g. the enzyme activity value of blood can be used to localise a diseased position and the extent of the illness. The determn. of the concns. of amino-transferase and aspartite-transferase in blood is useful for the diagnosis of liver diseases.

Title: Measuring method for assessing the quality of speech coders and/or transmission routes
Inventor: ZINKE JOACHIM
IPC: G10L25/69
Filed: 1987-03-12
Abstract: In the measuring method according to the invention, speech samples and/or test signals, from which a speech recogniser or speaker recogniser has previously formed a reference pattern during a learning phase, are presented to this speech recogniser or speaker recogniser via a speech coder to be assessed or a transmission route to be tested. Using an evaluation computer a comparison is carried out between the true meaning provided from a transmission memory and the meaning of a speech sample or a test signal recognised by the speech recogniser or speaker recogniser. In this process, an error rate or a measure of the reliability of recognition is simultaneously calculated over a measurement cycle.

Title: Process and apparatus for producing a zip-fastener tape half from a carrier tape and a woven-on helical row of fastener links
Inventor: HEIMBERGER HELMUT
IPC: A44B19/54
Filed: 1987-11-11
Abstract: Process for producing a zip-fastener tape half from a carrier tape and a woven-on helical row of fastener links consisting of plastic monofilament, the fastener links of which have a predetermined spacing and connecting parts. In a needle-type weaving machine, a carrier tape is woven from weft threads and warp threads at a weaving station. The row of fastener links is fed to the weaving station with low tension in the warp-thread direction, specifically by means of a driven feed device engaging positively into the row of fastener links and coordinated with the weaving progress. At the weaving station, tie-in warp threads engage in places over the individual fastener links and tie-in weft threads engage in places over the connecting parts. The repeat of the insertion of the tie-in weft threads is coordinated with the spacing. A special row of fastener links is fed to the weaving station, namely one which has a textile filling core round which the fastener links are looped and which is contracted by the tie-in weft threads during the weaving-in operation. The filling core is grasped positively by the feed device. The feed device is arranged directly in front of the weaving station. A pull directed away from the feed device is exerted on the row of fastener links entering the feed device, including the filling core. An apparatus for carrying out the process is also specified.

Patent DE-3805851-A1 (DE)
Inventor: SEIBOLD GERHARD DIPL ING
IPC: H05K7/20
Filed: 1988-02-25
Abstract: In order to dissipate the greatly increasing power loss resulting from the increasing integration density of semiconductor components, such that the components are not damaged, nowadays it is often no longer adequate to conduct the heat away via the printed-circuit board or to dissipate the heat by convection; additional cooling of the printed-circuit board must then be provided. It is known, for example, for the printed-circuit board to be mounted on a hollow copper plate which has cooling channels passing through it. It is very costly to produce such a copper plate. The idea of the invention is to use the printed-circuit board itself as a cooling device. The printed-circuit board consists of two outer layers (2) and at least one inner layer (4) which are bonded to one another or are connected to one another using a prepreg, by means of hot pressing. Slots or cut-outs are milled, stamped or cut out of the inner layer (4), which slots or cut-outs form channels (5), once the outer layers (2) are fitted, through which a cooling fluid flows.

Title: Device for preventing domestic washing devices from overheating
Inventor: HUBER HEINRICH
IPC: D06F39/04
Filed: 1988-03-30
Abstract: Known devices for protecting against overheating have a second control element which is in series electrically with the operation controller and in the event of a breakdown is operated mechanically via the linear extension of the heating element. The means of protecting against overheating, according to the invention, is intended to interrupt the heating circuit in an intrinsically safe manner in the event of a breakdown without mechanical aids and without additional control elements and in a sufficiently prompt manner that the device is not burned. A jacketed heating element (6), which is arranged in a pocket (4) at the lowest point of a plastic washing-solution container (1), is surrounded virtually on all sides by two plastic containers (7, 8) filled with fire-inhibiting substances. When the operational thermostat runs dry or fails, the bottom of the plastic container (8) melts as a result of overheating and empties its filling, which comprises sand or the like, onto the glowing jacketed heating element (6). Its heat dissipation is, by this means, reduced in such a manner that by internal overheating its heating coil is burnt through and the current feed is interrupted. The device for preventing the overheating is suitable for use in washing devices having plastic washing-solution containers. <IMAGE>
Patent DE-3811824-A1 (DE)
Inventor: KAJANTO ISKO
IPC: G01J5/10
Filed: 1988-04-08
Abstract: A fibre-optic temperature sensor utilises the variations in transmission of a mono- or poly crystalline semiconductor with indirect transition energy gap 14, to radiation of wavelength shorter than the absorption threshold wavelength of the semiconductor. A light source 10 generates the radiation which is guided via a first optical fiber 12 to a temperature- sensitive element 14 located at the measurement point, and light passing through the temperature-sensitive element 14 is guided via another optical fiber 16 for detection to a detector 18 in order to determine the temperature. A second source may provide a reference wavelength longer than the absorption threshold wavelength or both wavelengths may be derived, by filters from a single wideband source. The temperature sensitive material 14 may be silicon or germanium and may have a reflective coating on one face. The sensor achieves temperature measurement over a wide range of several hundred kelvins.   <IMAGE>
